Question

Which tissue develops from primary endosperm nucleus ?

Answer 1

One sperm nucleus fertilizes the egg cell, forming a zygote, while the other sperm nucleus usually fuses with the binucleate central cell, forming a primary endosperm cell (its nucleus is often called the triple fusion nucleus). That cell created in the process of double fertilization develops into the endosperm.

Answer 2

The endosperm is formed from the 'primary endosperm nucleus' by the 'repeated divisions'.  

Explanation:

• It is used as the main food for the embryo of the angiosperm. The 'central cell' is the most important cell which performs the various functions for the embryo sac.
• The endosperm nuclei increased the size during the development process. The primary endosperm is a triploid cell and is formed after the vegetative fertilization, triple fusion of the male gamete with the secondary nuclei of the central cell.
